I think the situation will improve, but it seems to be an uphill battle against corruption in the regulatory bodies.
I do wish there were more software employed for the enforcement. e.g. it's blatantly obvious that there is insider trading if you examine spikes in volume prior to M&A announcements. I can't imagine it would be that hard to mine the transaction data for offenders.
But as the article says, you can't build up a good database of evidence if you are regularly purging the data.
